CABLE-GRIP FOR LOGGING AND OTHER PURPOSES.

SPECIFICATION forming part of Letters Patent No. 526,224, datedSeptember 18, 1894. Application filed January 13, 1894. Serial No.496,773. (No model.)

To all whom it may concern.-

Be it known that I, GILBERT GAGNON, of Nanaimo,in the Province ofBritish Columbia and Dominion of Canada, have invented a new andImproved Cable-Grip for Logging and other Purposes, of which thefollowing is a full, clear, and exact description.

The object of the invention is to provide an improved and efficientgrip,in which the drag or resistance of the log or other object beinghauled and also the draft of the cable, are utilized in maintaining thejaws closed on the cable.

The invention consists in the novel features hereinafter pointed outanddefined in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the figures.

Figure 1 is a side elevation of a cablegrip constructed in accordancewith my invention, showing the same in the open position. Fig. 2 is asimilar view, showing the grip closed; and Fig. 3 is a front elevation,partly in section.

In constructing a cable grip embodying my invention, the fixed jaw A isformed at the bottom edge of the vertically-disposed plate or body B,and is rounded on the under side, as shown, to form a runner, thusspecially adapting the grip to logging purposes. Above the fixed jaw Ais arranged the movable jaw A, which is pivoted between arms 0 thatproject from the under side of a lever O, which in turn is fulcrumed atone end on a pin D that extends laterally from a body B of the grip, andformed at its free end with an eye 0, or an equivalent device, foraffording proper attachment of a rope, chain or cable E, to which thelog or other object to be hauled is connected.

At the rear of the grip is an arm F, which ranges upwardly andrearwardly, and at its outer end said arm F is given a forked formationby producing thereon an L-shaped arm H, which extends laterally from themain arm F, as at h and then parallel with the latter as at h, andthrough the fork thus provided is passed the pin 9 of a grooved orconcaved idler G.

The rope or cable E, which is secured to the lever G, as abovementioned, passes under the idler G, and is secured to the log or otherobj ect (not shown) in any suitable manner, and the member h of arm Hforms a guard or keeper for such rope.

The movable jaw A is supported from the lever O at a point between thefulcrum and free end of said lever, whereby it is movable bodily in anarc of which the fulcrum pin D of the lever is the center, and inaddition it is free to rock on its pivot to assume a position parallelwith the draft cable 10. In operation, the movable jaw having beenclosed on the draft cable 10, and the connecting rope or chain E of thelog being taut, when the draft cable is caused to travel, the drag orresistance of the log or other object, will be exerted to pull down thelever O, causing the movable jaw to be firmly pressed against the cable,and in addition, the draft of the cable 10 will also tend to maintainthe jaw closed, as the latter will in a measure act as a cam in responseto the forward pull of the cable. A retainer is provided for preventingthe accidental unshipping of the grip by a lateral movement, such.retainer consisting of an arm or latch I, which is pivoted on thefulcrum pin D of the lever O, or other suitable part of the grip, saidarm being movable across the space between the jaws, at the outside ofthe latter, and terminating at its free end in a hook e', which isadapted to engage a stud K, formed on the side of the fixed jaw, thestud preferably having a depending outer end is. When the grip is to beentirely removed from the draft cable, the arm I, is unhooked from thestud K, and the movable jaw raised.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A cable grip, comprising a body having a fixedjaw, a movable jaw arranged in connection therewith, a lever fulcrumedat one end to the body, to which lever the movable jaw is pivoted at apoint intermediate of the fulcrum and free end of the lever, and meansfor connecting the free end of the lever with the log or other object tobe hauled, substantially as described.

2. A cable grip, comprisinga suitable body,

gripping jaws, a lever to which one of said aws is pivoted, at a pointintermediate the fulcrum and free end of the lever, and means forconnecting the free end of the lever with a log or other object to behauled, substantially as described.

3. The combination in a cable grip, of a body having a fixed jaw andformed with a rounded surface on the under side to form a runner, thebody further being provided with a rearwardlyextending arm, a leverfulcrumed on the body'above the fixed jaw, a

movable jaw pivoted on the lever between its fulcrum and freeend, a ropeor the like for connecting the lever with the log or other object to behauled, and an idler on the rearwardly-projecting arm of the grip,around which said rope passes, substantially as described.

4. The combination in a cable grip, of a body having a fixed jaw andprovided with a rearwardly-extendin g arm, a lever f ulcrumed on thebody at the upper end of the latter and formed Witharms at its underside and with an eye at its free end, a movable jaw pivoted on the leverintermediate of its fulcrum and free end, an idler pulley on therearwardlyextending arm of the body, an L-shaped or forked formation onsaid arm, consisting of a branch arm, which ranges by its one arm acrossthe face or periphery of the idler, and is united to therearwardly-extending arm of the body, a retainer arm pivoted at theupper end of the body, adapted to swing across the jaws at the outsideand'formed with a hooked end, and a catch stud for said arm,substantially as described;

GILBERT GAGNON.
